Fuel Pressure Regulators

Fuel Regulator

Fuel parts are very important to achieve "big power." The HKS Fuel Delivery Kit does not include injectors, fuel line parts, and a regulator. To use this kit, the injector must be a stock or select one from the HKS Top Feed Type Injectors of 550cc, 680cc, or 1000cc. The fuel line parts must be Aeroquip's and the regulator must be HKS Adjustable Regulator.

(Extreme initial pressure change may cause bad atomization. Also, it increases the load to the fuel pump; in this case, the fuel pump may have to be replaced.)


  • Pressure Adjustable Range
    200-490kPa (2.0-5.0kgf/cm2)
  • Factory Setting
    290±19kPa(3.0±0.2kgf/cm2)
